The present invention relates to a sound motion converting apparatus for converting sounds into motion, and in particular, a sound motion converting apparatus for minimizing the time interval between the generation of sound and the implementation of the motion so as to feel a sense of unity of motion and motion, and having the same. It's about toys.

1 is a block diagram showing an embodiment of a sound motion conversion apparatus according to the prior art.

Referring to FIG. 1, the converter according to the related art includes a microphone 1, an amplifier circuit 2 for amplifying a sound input through the microphone 1, and a sound input through the amplifier circuit 2. A sound output unit 6 which comprises a determination circuit 3 for detecting the frequency of the signal, a switch 5 for manually operating the toy, and an amplifying circuit and a speaker (not shown) for amplifying and outputting an input signal. A driving unit 7 driven by a predetermined control signal to drive a motor (not shown); A light emitting unit 8 composed of a plurality of LEDs and emitting light by a predetermined control signal, the amplifier circuit 2, the determination circuit 3, the switch 5, the sound output unit 6, and the driving unit Connected between the 7 and the light emitting unit 8, when a signal of a predetermined frequency is input through the microphone 1, the sound output unit 6, the driving unit 7 and the light emitting unit 8 The controller 4 is configured to control an operation to output a melody, perform a prescribed movement, and perform an operation of emitting an LED.

The conventional toy configured as described above continuously detects a signal input from the microphone 1 and outputs a melody when a sound of a predetermined frequency (for example, a whistle, claps, etc.) is input, moves, and emits light. do.

However, since the converter according to the prior art converts the detected sound into motion, since a driving device such as a motor is used, it takes a predetermined time until the motion is performed by driving the motor, so that the sound is generated between the sound and the motion. There is a problem in that the time difference occurs and the completeness of the product falls.

For example, when the drum-beating drum is applied to a toy having a drum sound, the sound is already generated and the motion is implemented after a predetermined time has elapsed.

The present invention has been made to improve the above-mentioned problems of the prior art, a sound motion conversion apparatus for minimizing the time interval between the generation of the sound and the implementation of the motion so that it can be recognized as the sound generated by the motion implementation and the same The object is to provide a toy provided.

Sound motion conversion apparatus according to the present invention for solving the above problems is a microphone for detecting the sound, a band pass filter for passing a frequency of a specific band in the voice signal detected from the microphone, the voice signal passed through the band pass filter An amplifier for amplifying the, characterized in that it comprises a driving means for converting the voice signal amplified by the amplifier into an electromagnetic force to implement the operation.

Hereinafter, with reference to the accompanying drawings an embodiment of a sound motion converter and a toy having the same according to the present invention will be described in detail.

For convenience of explanation, a toy having a sound motion converter will be described as an example.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator.

Therefore, the definitions of these terms should be made based on the contents throughout the specification.

Figure 2 is a block diagram showing a sound motion changing apparatus according to the present invention, Figure 3 is a block diagram showing a toy having a sound motion converting apparatus according to the present invention.

2 and 3, the sound motion conversion apparatus according to the present invention includes a microphone 10 for detecting sound and a band pass filter for passing a frequency of a specific band in a voice signal detected from the microphone 10. Pass Filter 20, an amplifier 30 for amplifying a voice signal passing through the band pass filter 20, and a driving means 50 for converting the voice signal amplified by the amplifier 30 into electromagnetic force to implement an operation. It includes.

As a result, when a sound is generated, the microphone 10 detects it to generate a voice signal, and the voice signal generated by the microphone 10 passes through the band pass filter 20, and only a frequency of a specific frequency band is band pass. It passes through the filter 20.

The filtered voice signal of the specific frequency band is passed through the amplifier 30 so that the amplitude of the voice signal is increased, thereby easily switching from the driving means 50 to the electromagnetic force.

Here, the driving means 50 is a case 52, a coil 56 installed in the case 52 and electrically connected to the amplifier 30, and a magnetic body 54 which is installed on the case 52 so that it can be projected. And an elastic member 58 interposed between the magnetic body 54 and the case 52.

When the voice signal is transmitted to the coil 56 by the above-described configuration, the electrical signal circulates along the circumferential surface of the case 52 along the coil 56, and the electrical signal flows around the case 52. Magnetic field is generated.

This magnetic field interferes with the magnetic body 54 installed inside the case 52 to generate the flow of the magnetic body 54.

When the magnetic field is formed around the case 52, the magnetic body 54 flows in one direction due to the interference with the magnetic body 54. The direction of movement of the magnetic body 54 is determined according to the direction in which the coil 56 is wound.

In addition, when the generation of the sound is stopped and the signal supply to the coil 56 is stopped, the magnetic field formed in the case 52 is released, and the magnetic body 54 is again inside the case 52 by the restoring force of the elastic member 58. Is inserted into.

Looking at the operation of the sound motion converter according to the present invention configured as described above and an embodiment of the toy having the same as follows.

First, when a sound such as music is generated, the microphone 10 detects it and outputs a voice signal. The voice signal output from the microphone 10 passes through the band pass filter 20, and only a frequency of a specific band is passed. Therefore, the frequency of the other bands is filtered out, so that the user can obtain the frequency of the desired band.

For example, when music in which a plurality of musical instruments are played simultaneously is generated, only the frequencies of a specific band occupied by the drum can be extracted by the band pass filter 20.

Since the extracted voice signal increases in amplitude while passing through the amplifier 30, a larger amount of magnetic field can be formed when passing through the coil 56.

As a magnetic field is formed around the case 52 by the voice signal passing through the coil 56, the case 52 in which the coil 56 is wound has an electrode formed like a characteristic of an electromagnet, and slides inside the case 52. The magnetic material 54 is magnetically interfered with the magnetic material 54 which is possibly installed, so that the magnetic material 54 flows in one direction.

After the generation of the sound is stopped, the voice signal transmitted to the coil 56 is stopped, so that the magnetic field generated around the case 52 disappears and the flow of the magnetic body 54 is also stopped, and the magnetic body 54 is an elastic member ( It is inserted into the case 52 by the restoring force of 58).

In addition, when the generation of the sound occurs regularly, the operation as described above is continuously repeated, and when applied to the toy as shown in Figure 3 it is possible to implement the operation to continuously beat the drum.

At this time, since the driving means 50 according to the present invention converts the motion only by electric and magnetic forces without a separate driving device such as a motor or a pump, there is no time required for power transmission except for the time required to transmit a voice signal. The generation of sound and the realization of the motion are almost simultaneously.

As a result, when the sound motion converter of the present invention is applied to the doll hitting the drum as shown in FIG. 3, only the frequency of the band corresponding to the drum sound is extracted from the music sound generated indoors. Every time is generated an operation of tapping the drum by the doll is implemented.

At this time, since the time difference between the generation of the voice signal and the implementation of the operation is hardly generated, it can be perceived as if a doll is generated by hitting a drum.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art. Will understand.

In addition, although the sound motion converter and the toy having the same has been described as an example, this is merely exemplary, the sound motion converter of the present invention can be used in other products than the sound motion converter used in the toy.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.

The sound motion conversion device and the toy having the same according to the present invention configured as described above are arranged so that the magnetic material is disposed inside the magnetic field generated by the flow of the voice signal without a separate driving device, thereby generating an electromagnetic force simultaneously with the supply of the voice signal. The magnetic force is induced by the electromagnetic force, and the movement is realized at the same time as the generation of the sound. Therefore, it can be seen that the sound is generated by the implementation of the motion when the user sees it. Accordingly, there is an advantage that the user's satisfaction can also be increased.
